RES PIRATO R.

SPECIFICATION forming part of Letters Patent No. 712,304, dated October 28, 1902.

Application filed June 5, 1902. Serial No. 110,304. (No model.)

To @ZZ whom it may concern,.-

Beit known that we, MAURICE JACOBS, of the city of New York, borough of Manhattan, in the county of New York, and ARCHIBALD P. BLACK, of the city of New York, borough of Brooklyn, in the county of Kings, State of New York, citizens of the United States, have invented a new and Improved Respirator, of which the following is a full, clear, and exact description. y

This invention relates to improvements in respirators or shields designed to be placed over a persons mouth, the object being to provide a device of this character of very light construction and so arranged that it may be easily held in position without employing' unsightly strings or elastics for passing arounda persons head.

Afurther object is to provide means whereby the device may be used`as an inhaler of medicaments.

We will describe a respirator embodying our invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view showing a respirator embodying our invention and in position. Fig. 2 is an inside view of the device. Fig. 3 is a cross-section thereof. Fig. 4. is an inside view showing a slight modication, and Eig. 5 is a longitudinal section of the device shown in Fig. 4.

The respirator l consists of a body portion 2, in which for the sake of lightness aluminium or the like is employed. This body portion is provided with perforations, and on the outer or front side is a covering 3, of silk or other suitable fabric, and extended around the inner edge is a cushion 4, which will hold the body portion suflciently far from a persons lips and will also prevent any possible scratching of the face. Between the metal and outer cover a thin sheet of cork 3n` may be placed. This cork serves as a non-conductor of heat in summer and of cold in winter.

As a means for holding the device in position in Figs. 2 and 3 we have shown a loop 5,

of soft rubber, that is suitably secured to the center of the body portion and projects sufijciently outward to be grasped by a persons lips or teeth. In Figs. 4 and 5 this holding 55 device consists of a single strip of soft rubber 6.

Secured to the inner side of the body portion and here shown as at near one end is a clip 7 for holding a sponge" or pad 8, which 6c may be saturated with medicine when the device is to be used as an inhaler. We also may employ at one edge clips 9 for holding a sponge or pad 10 for medicine t0 be inhaled through the nostrils.

While we have shown the device as oval in outline, it is obvious that it may be otherwise shaped without departing from the spirit of our invention, although the shape shown may be preferable.

This respirator requires no outside attachment whatever.- It is simply placed over the mouth and held bythe teeth or lips and may be instantly applied or removed, and it is of such a size that itmay be carried in a persons pocket. It is apositive protection against inhaling microbe-ladened dust in summer and tempers and filters the cold air in winter. Many dangers may be avoided by its use by firemen, Workers in factories, flour- 8o mills, coal-mines, and lead-works, by chemists, doctors, nurses, and travelers, and by all persons exposed to malarial atmosphere. As an inhaler of such medicaments as chloroform, menthol, turpentine, dac., the device will serve the same purpose as a more expensive and cumbrous device.

Having thus described our invention, we claim as new and desire to secure by Letters Patent-` 1. A respirator, comprising a perforated body portion, a textile outer covering, a cushion extended around the inner edge of the body portion, and a strap of yielding material extended inward from the center of the 95 body portion, substantially as specified.

2. A respirator, comprisingv a Vperforated body portion of metal, means for Aholding the device in position, and a pad-holding clip on the inner side of the body portion, substanroo Jrially as specified.

3. A respirator, comprising a perforated body portion, a soft-rubber loop extended names to this specification in the presence of from about the' center of the body portion, tWo subscribing Witnesses.

an outer covering on the body portion, a oush- MAURICE JACOBS. ion extended around the inner edge of the ARCHIBALD P. BLACK. 5 bod)` portion, and pad-holding devices on the Witnesses:

respirator, substantially as specified. D. C. WHEARTY,

In testimony whereof we have signed our HARRY R. CLARK.
